Constructor Detail

UberspectImpl

public UberspectImpl()

Method Detail

init

public void init()

init - generates the Introspector. As the setup code makes sure that the log gets set before this is called, we can initialize the Introspector using the log object.

Specified by:

init in interface Uberspect

setLog

public void setLog(org.slf4j.Logger log)

Sets the runtime logger - this must be called before anything else.

Specified by:

setLog in interface UberspectLoggable

Parameters:

log - The logger instance to use.

Since:

1.5
